Problems solved by technology

The existing system adopts the method of setting the parameters in the program to configure the radar parameters. It is impossible to modify the parameters such as the radar data fusion threshold, the static weighting value and the dynamic weighting value of the radars participating in the fusion. Any change of these parameters requires the programmer Technical support, lack of flexibility, poor operability
[0007] 3. In the process of radar data tracking and processing, data receiving, decoding, and processing have high requirements for real-time performance. In the radar processing system, single-threaded programming technology is adopted, and radar data receiving and tracking processing are carried out cyclically, which may easily cause data loss. Radar It is particularly important whether the terminal can receive radar data in real time and accurately

Embodiment Construction

[0035] The multi-monitoring source flight target parallel tracking processing system designed by the present invention includes five parts: data receiving, data preprocessing, radar data processing, ADS-B data processing and fusion data processing, and its flow is as follows figure 1 shown.

[0036] In the parallel tracking process of flying targets with multiple monitoring sources, the data of each radar head and ADS-B data must be obtained first and stored in the database. Then these data need to be verified, classified and some erroneous data should be eliminated. The target track obtained in one scanning cycle of the single radar is tracked and processed by the radar processor, and the track data of the single radar is generated, and the state estimation of the target is given. At the same time, radar local tracks are generated through multi-radar data processing. According to the same processing flow, ADS-B point track is processed to generate single ADS-B track and ADS...

Abstract

The invention discloses a multi-surveillance-source flying target parallel track processing method. The method includes the steps: multi-surveillance-source data receiving; multi-surveillance-source data analysis; radar data processing; ADS-B (automatic dependent surveillance-broadcast) data processing; multi-surveillance-source data fusion. Surveillance of quality of data accessing to radar is realized by monitoring and analyzing quality of radar signals. In addition, real-time receive processing of the radar data is realized by means of multithreading, high safety, high reliability and high usability of a data processing system can be further guaranteed, and accuracy and quickness in track processing of flying targets in different data types from different surveillance sources can be realized.

Description

technical field [0001] The invention relates to a multi-monitoring source flying target parallel tracking processing method. Background technique [0002] At present, air traffic control basically relies on radar surveillance and very high frequency (VHF) communication, both of which are limited by line-of-sight propagation, and the coverage range is relatively small. Due to the limitations of various factors, radar and VHF coverage cannot be achieved in the vast ocean airspace and remote mountains, deserts or jungle areas, resulting in blind spots in the flight airspace and bringing hidden dangers to flight safety. In order to overcome these shortcomings and achieve effective air traffic surveillance, the International Civil Aviation Organization (ICAO: International Civil Aviation Organization) proposed a new concept of surveillance, based on the application of satellite technology in the future air traffic surveillance, which is automatic Related monitoring (ADS: Automat...
